Due a break in the good weather

The good weather of the last four weeks has benefited all the young birds that have recently fledged. We have not had more than 3mm of rain in a day since I last blogged , which has facilitated opening the net on five days out of seven. The breeze has been strong at times especially in the afternoons when it has had a welcome cooling effect. Today the weather is on the turn and the barometer is on the way down for the first time in ages. The warm and sunny days have been good for the soft fruit and a period of rain should benefit the apples and pears.

Having said that, the young birds have done well, going by the amount of bird food that has "disappeared", and I have caught juveniles almost exclusively in the last four weeks or so. Six more young Jackdaws 'found the net'.

 We are seeing second and third broods of Robins, a species that seems to do well around here. Just had to take a couple of pics!

One of the Pied Wagtails had obviously been naughty and sent to bed without its tea, going by the severe growth bar on its tail ( or rather, lack of growth). At some time in the near future the tail will snap off at this point. Incidentally, one of the other young wagtails has already lost its tail completely.

 It has been good to catch a few Coal Tits. They used to breed in our large conifers but we had to take down the three nearest the house (very near!) for insurance purposes and they now breed over the road. The numbers of Blue Tits on the feeders has also jumped up; although they fledge later than their big cousins, the Great Tits, they start their post-juvenile moult earlier, something that only ringers really appreciate.

Now for the ringing list covering the last month:

Collared Dove - 2; an adult and a f.g. bird of the year
Kingfisher - 3; all juvs
Gt. Spotted Woodpecker - 2 (1); retrap female and (presumably) her offspring
Jackdaw - 6; all juvs
Goldcrest - 2; both juvs
Blue Tit - 22 (3); all 25 were juvs
Great Tit - 17 (1); all 18 were juvs,, 7 of which were frequent "visitors" 
Coal Tit - 3; all juvs
Swallow - 2; both juvs
Long-tailed Tit - 4 (8); all juvs
Chiffchaff - 3; juvs
Blackcap - 13; 3x 2CY males, 2x 2CY females plus 8 juvs
C. Whitethroat - 1; a juv
Wren - 5; a female & 4 juvs
Blackbird - 11 (6); 2x adult females, 5 adult males (y new) & 10 juvs
Robin - 11 (4); a male, a 4 year old female, 13 juvs with multiple captures
Dunnock - 16 (5); a male, a female retrapped plus 19 juvs
House Sparrow - 16 (12); 3 r/t males & 2 new, with 23 young. 
Grey Wagtail - 1; 2CY breeding female
Pied Wagtail - 2; both juveniles; 2 unringed juvs also visiting daily
Chaffinch - 28; all juvs, none retrapped
Bullfinch - 1; breeding 2CY female
Greenfinch - 27 (3); a male & a female retrapped, 4 new males & 24 youngsters (10 male, 13 female, with 1 left unsexed due to confusing 'signals')
Linnet - 1; a cracking 2CY male (sorry, no photo)
Goldfinch - 53 (11); 9 were adult males, 6 adult females and the 49 others all young birds
Siskin - 5; 1x 3M, 2x 3F, 1x 5F, 1x 4M

That's 259 new rings attached and 54 other birds recaptured, quite a few more than once.

261 were this years hatchlings and comprised 83.4% of the total catch. Of these, I surmise that only some 80 will survive the coming winter and that I will re-capture just 30-35 of those in the next calendar year, allowing for abmigration and the vagaries of catching.

We have been playing host to a stray racing pigeon for the last couple of months. It has even wandered into the garage to find the source of all that lovely bird seed that gets put out on the lawn. Although only 25 miles from home, the owner would have to travel 86 miles each way and pay the Severn crossing toll! Not worth it for a 10 year old bird.

At last the buddleia is in full flower and the Peacock butties have reappeared. So have several other species including the much loved Gatekeeper, one of my favourites. Also we were able to supplement our stock of "worms", courtesy of a neighbour.

Family of Slowworms

During a break from writing this, a family party of Ravens, 2 parents and 2 offspring, flew  westwards over the garden. 

Post-script: we had 37 mm of much anticipated rain in 24 hours and strong winds.

Sauntering up to the Summer Solstice

This post covers the three week run-up to the longest day.

Things are busy in the garden - grass to manage, hedges to cut, borders to weed, soft fruit to pick, black-fly to purge, vegetables to tend, water and harvest, and so it goes on. At least the new potting shed is finished and the greenhouse glass repaired.

The birds have been busy too, mostly feeding their young on either natural food or that which I have provided. So far this year, I have gone through 120kg of SFH, 25kg of suet, 15kg of 'finch seed' (fine stuff) and 10kg of dried mealworms. Haven't counted the packets of sultanas! And dread to think of the cost, too. However, time to replenish stocks!

From now on, the amount of bird-food that I will be putting out will drop off considerably, allowing the birds to return to their natural diet in the countryside/farmland/housing estates. Come November, when the fog and first frosts should appear, I will start feeding more heavily. I find that the greatest demand is either during periods of snow or lengthy frosts and immediately prior to and during the breeding season. By easing off, usually by putting out food just the once 'early doors', the birds are driven to follow their natural instincts for the rest of the day. This weeds out "the chaff from the straw", leaving the fittest to make it round to next year's breeding season. 

For Goldfinch aficionados, have a look at Peter Alker's blog here; you might want to tear out the id pages from Svensson after reading this.

Now for some pictures of very young birds that have been caught recently. With still a lot of growing to do, especially of their flight feathers, it's a marvel that they manage to fly so strongly. We quite often find them high up in the nets.

A really good total for the time of year - often we are away for a week in June, so the fact that we weren't this year might have helped!

200 new birds and some 40 birds from previous.
Herring Gull - 1; a beautiful adult in moult
Woodpigeon - 0; couldn't get to it in time!
Collared Dove - 3;
Gt. Spotted Woodpecker - 2; a pair busy provisioning their young from the feeder
Jackdaw - 1; a youngster
Rook - 1; a too enthusiastic female
Blue Tit - 16 (1); a male from November 2011 (4M)
Great Tit - 12;
Swallow - 3; a first brood about 10-12 days old
Long-tailed Tit - 19 (3); all in one go!
Blackcap - 4 (2); mum & dad first, then four youngsters
Nuthatch - 1; a juvenile was an unexpected first for the garden (doesn't breed in our tetrad, a 2x2km grid square)
Wren - 2;
Starling - 5;
Blackbird - 13 (4); two birds from autumn 2013
Robin - 13 (5); our old female yet again (born here in spring 2011)
Spotted Flycatcher - 2; a pair caught together late morning on the 7th, another first!

male & female Spotted Flycatcher, June 2015
(not separable on plumage)

Dunnock - 11 (4);
House Sparrow - 32 (8); oldest a 2012 youngster
Pied Wagtail - 1; "old peg-leg", an adult (3cy) back in July 2012
Chaffinch - 6  (2);
Greenfinch - 28 (2); the real surprise - lots of new young birds
Goldfinch - 22 (8); just 3 adults - that were all male
Siskin - 5;

Over the half-way mark (750) for new birds this year and hopefully about ten more species to get as well, going by previous years. Nothing's  guaranteed in this game though!

PS. I buy much of my bird-food in bulk direct from the importers/processors/wholesalers to reduce costs. It is stored in plastic dustbins to deter the Wood Mice.

The last days of (meteorological) spring

The Met. men start off their summer statistics from today - but the gardeners will wait another three weeks until the summer solstice before they agree on that. At least we shouldn't get any frosts for the next three months. Cold rain, gales, low cloud perhaps!

The birds are either busy nesting, i.e. sitting on eggs for the first or even second time, or trying to find enough food to satisfy their hungry chicks, or even trying to educate their flying offspring in the ways of this very human dominated world. This gives us ringers a warm feeling, as we should be kept very busy ringing the next generations at this time.

Pullus Blue Tit - ca. 10-11 days old (May 2015)

We had a trip to the Field Studies Centre, ostensibly to ring some tits in a box. Unfortunately five eggs didn't hatch, leaving just three pulli alive. The cold weather and the rain that washed many of the insects off the trees have certainly caused their stunted

growth; they would normally have been much further advanced by this time. We played around with some potential net sites and were comforted with a further eight adult birds, including the mother of the chicks. It's all mod-con here!

Nettlecombe base

The Jackdaws are coming "en masse" every morning as soon as I put out the suet pellets on the several bird tables. They are quite acrobatic and manoeuvre around the nets and other obstructions quite intelligently. One, maybe two, got caught out but I was unable to retrieve any for ringing this time. Slippery as an eel!

The "bright spot" of the last fortnight has to be the large number of House Sparrows caught, now amounting to 77 'new-for-year' individuals.

In all, we ringed 82 new birds, 11 of these at Nettlecombe, and handled another 42 separate birds. 

Recently fledged 'spotty' Dunnock.

Collared Dove - 1; an early youngster starting wing moult

Jackdaw - 0; nearly but not good enough

Goldcrest - 1; adult female with a classic "club" tail

Swallow - 1;

Wren - 2 (1);

Starling - 3 (2); a single juvenile so far

Blackbird - 3 (7); a third juvenile male and nine adults

Robin - 5 (6); 7, 4 new, were juvs.

Dunnock - 9 (1); 9 youngsters and a 2CY female (caught 3 times)

House Sparrow - 23 (10); 27 young birds ringed so far in 2015

Chaffinch - 3 (1); 3 juvs, the first on 25th

Greenfinch - 8 (4); 6 new & 2 recaptured juveniles; oldest bird ringed as adult male in November 2012

Goldfinch - 11 (8); 10 new juveniles to add to the 6 already ringed;
oldest bird was an immature when ringed in November 2012

Siskin - 3;

A 'this year's' Siskin

Going slow but steady

Another fortnight has passed and the General Election is well out of the way. The birds took no notice of politics and carried on feeding and breeding. We have had some of our greatest numbers on the BTO Garden Birdwatch weekly counts, which is no surprise as the birdfood stocks have been going down at a record rate.

Two bits of news of birds caught here came through. The first was for a 2CY male Greenfinch that was ringed on Exmoor some 28 km south-west of here on "Bonfire Night" and controlled here 152 days later. The other of a Sparrowhawk caught by neighbouring veteran ringer, John, at the other end of the village in December 2009 as a young bird. I also caught a female Siskin with an 'unrecognised' ring sequence (D039) - we'll have to wait and see where that hailed from.

The iridescence of the Starling's plumage

We are hoping to ring some tit pulli in nest boxes this coming week. I get the impression that many species have laid slightly later this year, perhaps because of the cold spell and the general lack of normal amounts of rainfall, both contributing to later insect abundance. But I don't see much evidence so far that there are loads of insects about. 

The other task for the week ahead is the  recce of 3 rural squares for the House Martin survey. See http://www.bto.org/volunteer-surveys/house-martin-survey for more information. They were one of my first study species after I had returned to bird ringing. We picked up the start of the decline back in the 'eighties on the 'seventies estate we were surveying.

The first Swift has arrived

Although it is only two weeks since the last blog, several things have been noticeable, not least the sight of my first Swift of 2015 earlier this afternoon, flying over the garden.

We have not done a lot of ringing, mainly because I had to take to my bed with a temperature but also because Steve came to put the management's new, hand-built potting shed up. So, most of these records refer to the week before last. The last few days have been cold and temperatures below average for the time of year. The signs corroborated this with birds of all species ransacking the food I put out like there was no tomorrow. There was to be one, because I was putting out good quantities of the stuff (SFH, suet, mealworms & sultanas) three times a day!

On the other hand, we did get in a couple of early sessions down the meadows. Day 1 was warm with bright sunshine, Day 2 was dull, damp and cold. We managed to catch the local male Dipper (unringed) and both adults of a pair of Kingfishers nesting nearby. The treat was handling the 2CY female Blackcap bearing 'Paris7851989' on both occasions, even though we were using a different net set-up. With a 79.5 mm wing and weighing in at 21.5 grams the second time (up 1.5 g), she was a big girl with no signs of carrying much fat or of a brood patch.

Paris Blackcap

Female Kingfisher

1st Sedge Warbler of 2015 (24/04)

Other birds of note down there were a pair of Bullfinch, the first Sedge of the year, my first Swallows, just one of the Willow Warblers, a female, and a couple of territorial male Blackcaps that were 'lean and mean'. Most of the other birds were trapped in the garden orchard, before I went down with the lurgi. There was little point after the shed was up as the weather had changed for the worse.

Ninety birds of which 59 are new ringings. This includes the next lot of infant Robins, the first 3JJ Dunnocks and the first of the newly fledged Greenfinches (this Thursday 30th). Still no signs of any young Blackbirds coming to our lawns.  

Woodpigeon - 1; a small, underweight but feisty bird in active wing moult (3 centres), the first one to "stick" this year.

Kingfisher - 2; a pair

Blue Tit - (1)

Great Tit - 1 (4);

Swallow - 2; now back at the stables in good numbers

Chiffchaff - 1

Willow Warbler - 4; passage seems to have stopped about a week ago

Blackcap - 6 (2); even split on sex

Sedge Warbler - 1

Wren - 2 (2); one 'eggy' female

Starling - (1)

Dipper - 1; territorial male

Blackbird - 3 (2)

Robin - 6 (2)

Dunnock - 2; young bird on 25th

House Sparrow - (3)

Chaffinch - 2 (2); mixed ages/sexes, male from 2013,

Bullfinch - 2; an unexpected 2CY pair

Greenfinch - 6 (4); 50% adult males, 2 birds from 2012

Goldfinch - 16 (8); two-thirds males, still some passage going on, weights >18 g

Siskin - 1; breeding female on 18th (BP4)

One bird missing off this list is Redstart - a calling individual was heard for about 30 minutes in the tops of the Ash trees while we were putting the roof on the shed.
